Electrochemical study of the catalytic influence of sulfolobus metallicus in the bioleaching of chalcopyrite at 70 degrees c
(ELSEVIER SCIENCE BV, 2006)
The catalytic influence of Sulfolobus metallicus in bioleaching of chalcopyrite at 70 degrees C and pH 1.7 was characterized from studies of anodic dissolution of a chalcopyrite concentrate at constant potential. Experiments ...
Graphene in Lithium-Ion/Lithium-Sulfur Batteries
(Wiley, 2019)
In order to deal with the energy demand of the increasing global population,the use of sustainable sources of energy has become mandatory to attenuate theenvironmental problems that come along with the use of fossil sources ...
A top-down approach to build Li2S@rGO cathode composites for high-loading lithium–sulfur batteries in carbonate-based electrolyte
(Pergamon-Elsevier Science Ltd, 2019-02)
With a notable advantage in terms of specific capacity (1166 mAh g−1), lithium disulfide (Li2S) has been considered a promising cathode material for high-energy-density lithium–sulfur (Li–S) batteries. In contrast to pure ...
Extracción de losartán de muestras acuosas empleando microfibras de polisulfona con aliquat 336
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2019)
Los fármacos antihipertensivos, como el losartán, después de ser consumidos son transportados al ambiente en donde pueden encontrarse en concentraciones bajas; por lo anterior es necesario desarrollar técnicas para remover ...
Isomers on the [H, S(2), Cl] potential energy surface: A high level investigation
(ELSEVIER SCIENCE BV, 2009)
This study reports a systematic state-of-the-art characterization of new sulfur-chlorine species on the [H, S(2), Cl] potential energy surface. Coupled cluster theory singles and doubles with perturbative contributions of ...
Dependence of the network structure of cured styrene butadiene rubber on the sulphur content
(Elsevier, 2004-12)
An investigation about the dependence of the physical properties of styrene-butadiene rubber copolymers (cured with different sulphur content, in order to obtain various networks) on the crosslink density was carried out ...
Control in vivo de Moniliophthora roreri en Theobroma cacao, utilizando polisulfuro de calcio y silicosulfocálcico
(Universidad Pedagógica y Tecnológica de Colombia, 2017-08-10)
Se evaluó en campo, bajo condiciones semicontroladas, la eficacia de los fungicidas minerales silicosulfocálcico (SSC) y polisulfuro de calcio (PC) para el control de la moniliasis [Moniliophthora roreri (Cif. & Par.)] ...
Oxidação de sulfetos promovida por materiais carbonáceos ativados
(Universidade Federal de Minas GeraisUFMG, 2010-02-26)
In this study, the use of activated carbons (ACs) to promote the oxidation of sulfide ions in solution was evaluated. Raman, IR, UV-Vis, XRD and TG/DTA data showed that the oxidation of sulfides led to the formation of ...
Construction of CdSSe/GO multilayer thin films for hybrid solar cells
(2015-10-21)
Multilayer films of graphene oxide (GO) and cadmium selenide nanoparticles (CdSSe) with and without molecular functionalization linkers were prepared by sequential electrophoretic deposition and dip-coating techniques for ...
